Kaijin Kaihatsu-bu no Kuroitsu-san

Synopsis

After hearing about the money and prestige that Valentine's Day brings in to different companies, Kuroitsu pitches a chocolate monster to the Agastia board based on its potential profitability. Both Megistus and Akashic approve of the idea. Akashic later visits the Monster Development Department to train Kuroitsu and Wolf Bete in making their own chocolate while working on a monster. Eventually, they create a chocolate-themed monster named Melty. However, news breaks that the vendor they bought the chocolate from had metal pieces embedded in the chocolate. Megistus refuses to release Melty against Blader, as he fears it would ruin Agastia's reputation to have a monster made of tainted chocolate. With no time left to make another monster, Kuroitsu simply hands over a basket full of the chocolate they made to Blader, along with a warning not to eat the remnants of Melty. Kenji is later overjoyed by the gift. Elsewhere, Hoen decides to arrange a friendly sparring match with her latest monsters that use psychological attacks against Agastia's Wolf Bete and Hydra, hoping to save her own position at Black Lore. However, both Black Lore monsters' attacks backfire against the unique traits of their opponents. Back at Black Lore's HQ, Bull Head uses his fear attack on the Red Mantle General, leading him to quickly resign from Black Lore.
